AI

Describe the part.
Get real, editable CAD.

The assistant does not draw a mesh or a picture. It builds the part with the Studio’s own tools, so you get sketches and features you can open and change, exactly as if you had made them.

  • Parts and assemblies
  • Photos and PDF drawings
  • One undo step per change
Built-in assistant

Three steps,
and you stay in charge.

Open the AI panel in the CAD Studio or the Assembly Studio. It sees the open document and works on it directly.

  1. 01

    Describe it

    Say what the part is and the sizes that matter. Attach a photo, a sketch or a PDF drawing if you have one.

  2. 02

    Watch it model

    The assistant sketches, extrudes, fillets and shells in your Studio. Each feature appears in the history as it is made.

  3. 03

    Make it yours

    Change any dimension, reorder or delete features, or ask for the next change. Every step it took is one undo.

Example: a request, and the features it turns into

Make a sensor box, 96 by 64 and 34 tall, with 2.4 mm walls, a screw boss in each corner and vent slots on one side.

Credits

Pay for what the AI does,
not for the CAD.

The Studios are free. The assistant comes with the paid plans and runs on credits: a quick question uses a few, building a whole part about 75.

  • Basic7,500credits a month · MXN 349
  • Max48,000credits a month · MXN 1,799

Need more? 2,000 extra credits cost MXN 99, and they do not expire.
